CYLINDER-STOP FOR REVOLVING FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 289,821, dated April 5,1881.

Application filed February 17, 18511. (No model.)

To all whom it may concern:

Be it known that I, HENRY MGGEE, of Norwich, in the county of New Londonand State of Connecticut, have invented a new and useful Improvement inRevolve and I do hereby declare that the following is a full, clear, andexact description of the same.

My invention is an improvement upon the patent granted December 10,1878,to A. L.

[0 Sweet. In that patent was shown a revolver wherein the cylinder waskept from revolving by a stop pivoted to the trigger and working in aslot in the bottom of the chamber which contained the cylinder, thecylinder being provided with corresponding slots into which the stopprojected.

The object of my invention is to simplify the construction and lessenthe cost and labor of manufacture; and itconsists in the peculiarconstruction and arrangement of the stop and the parts thatopcrate inconnection therewith, as fully hereinafter described.

In the drawings, laigure 1 is a central sec-,

tion of my pistol, and Fig. 2 is an enlarged detail view of the stop andspring.

In these drawings, A represents the cylinder of a revolver, and 1 1slots on its surface, there being as many slots as there are chambers inthe cylinder.

0 B is the hammer, and C the trigger, which are of the same generalconstruction as in the patent referred to.

I) is the stop. (Shown separately in Fig. 2.) lnstead of being pivotedto the trigger, as in the patent referred to, the stop is provided withan oli'sct, 2, hich engages with the lower edge of the recoil-shield,and vith a spur, 3, which rests on a projection, 4, on the upper forwardend of the trigger. The bottom of the 40 chamber which contains thecylinder is slotted, as shown, and in this slot the stop works, thelower edge oi. the recoil'shield serving as a fulcrum on which itswings. A spring, 5, serves to project the stop upward into its norandposition when it enters one of the slots on the cylinder, and holds itstationary. The ot't'set 2 holds the stop in position against'anylongitudinal movement, and its rear end is held up by resting on theprojection i of the trigger, so thatitis secured against movement in anydirection, except that necessary for its action, by means of its ownconstruction, and that of the parts in connection with which itisplaced.

It will be observed that the upper part of the trigger is bent forward.The projection 4 will therefore rise when the upper end of the triggeristhrown back; but the upper end of said trigger is kept in contact withthe rounded edge of the hammer, and the construction of this part issuch that it keeps the upper end of the trigger pressed forward farenough to permit the catch to be in gear with the cylinder at the propertime.

It will be understood that the spring5 tends constantly to hold thecatch in gear. The part of the hammer-piece against which the upper endof the trigger bears when the hammer is down, as in tiring, allows theupper end of the trigger to come back far enough to let the spring 5throw up the catch into gear with the barrel; but when the piece is athalf-cock the spur or upper end of the trigger falls back into thejnotch6, and in so moving throws up the rear end of the catch and depressesits front end. sutlieiently to release it from the notch in thecylinder. As the hammer is drawn back the relative position of theseparts is unchanged, and the catch is out of gear until the triggerengages with the notch 7 and is at full-cock, when the upper end of thetrigger is thrown forward snliicicntly to allow the spring 5 to throwthe catch or stop into connection with the cylinder. Thcrrelativemovement of the rawl is the same as usual,

It will be observed, from the description already given, that the samemovement of the stop is caused by the described construction asthatwhich has been accomplished heretofore by pivoting the catch uponthe trigger. 9o

lilanit'cstly the construction is inexpensive, the stop being of suchshape that it may be easily struck out, and thereis a saving of theexpense of pivoting this part upon the trigger.

it will be nnderstooi-l that the described con 5 structiou is speciallydesigned for revolvers of r0 edge of which acts as a fulcrum, and thespring 7. the less expensive class, although its efiicieucy 5, allsubstantially as described, and for the is not less than that upon whichit is an impurpose set forth. provement. t In testimony whereof I havesigned my name Having thus described my iuvention,what I to thisspecification in the presence of two sub- 5 claim as new; and desire tosecure by Letters scribing witnesses.
